Implication

Supports targeted lipid evaluation in premature CAD; leaves open whether identifying familial disorders improves outcomes.

Key Points

The study investigates the prevalence of genetic lipoprotein disorders in individuals with premature coronary artery disease (CAD).
Analyzed 102 kindreds (N=603 subjects) with significant CAD documented before 60 years of age.
Defined abnormal lipid levels based on fasting plasma cholesterol, triglyceride, LDL, and lipoprotein metrics compared to age- and sex-specific norms.
Assessed the correlation of biochemical variables within family units.
73.5% of probands exhibited lipid abnormalities compared to 38.2% of age-matched controls (p<0.001).
54% of probands were identified with a familial lipoprotein disorder, with Lp(a) excess (18.6%) and hypoalphalipoproteinemia (39.2%) being common.
Parent-offspring correlations indicated a genetic contribution to lipoprotein and apolipoprotein levels, especially Lp(a).

Age-matched controls

Outcome

Prevalence of familial lipoprotein or apolipoprotein disorderssurrogate

More than half of patients with premature CAD have a familial lipoprotein disorder, highlighting the importance of comprehensive lipid screening in this population.
